Answer:
Chemistry
Step-by-step explanation:
M. Waldman argues that chemistry is the branch of science in which the greatest improvements have been and may be made. However, Shelley's understanding of chemistry is different to the one we have nowadays. During the nineteenth century, chemistry was not only concerned with inorganic compounds. Instead, it also studied the functions of living beings (much like biology does nowadays). Therefore, Victor's work is thought to belong to the field of chemistry.
